Review on 🔌 Moes Dual Power Controller: 50A 5500W Automatic Transfer Switch for Off-Grid Solar/Wind Systems - ATS DC 12V 24V 48V AC 110V 220V by Nhyiraba Wilson

Pros: Works exactly as advertised: Switches to mains when voltage is lower than user specified. Allows me to avoid low voltage inverter shutdown during startup spikes and battery wear by avoiding using them below 75% charge. warns of a "smoldering fire" if something goes wrong. Contains little to no information on grounding the AC output line from the transfer switch. It's also not clear what is powering the LCD, which makes me panic if it doesn't run the LCD on battery power alone, for fear that an ungrounded faulty device could short out my house's AC lines. It turns out that powering the LCD and programming the device appear to require an AC connection. I grounded the battery negative terminal via an external pin and grounded the AC plug to the battery negative terminal. My ground sensing power strip claims to be grounded and there are no fires yet. Pooh!
